This invention relates .to AXmi-nster looms and it is the general objectyof the `invention to provide an improved tube frame and transportingchain to the ,end that the tube 5 frame may be .held more ,securelyjagainst accidental displacement with respect `to the transportingchain.

In my prior Patent No. `1,493,561 there is shown a transporting chainhaving projectving tongues which are adapted to be rinterlocked with atube frame having` a sliding locking bar. Actual operation of theconstruction shown in the aforesaid patent shows the desirability `ofbeing able Ato direct .the tongues. on lthe transporting chain moreaccurately `into operative `position `with respect [to the holdingplunger, and it is accordingly an important object of my resentinvention -to provide the brackets of .the tube frame and also the `clutch which releases the tube frame from the tongues withguidingsurfaces which operate to guide the tongue more .accuratelytoward the holding plunger when the .tube `frame is bein .attachedItothe transporting chain.

Itis also found .that the releasing tongue which is carriedby the clutch`may not operate to move the holding or interlocking,

plunger in properly retracted position .to

.30 effect complete release lof the attaching .fin-

, gers en ,the transporting chain and it is `a further object of myinventionf'to provide .a construction which will insure .releasing kofthe finger by the plunger.

It is a more specific object ofmy present invention to provide thereleasing tongue as a part of one of the studs customarily provided asa. part of the releasing clutch.

Experience has shown that the plunger shown ,in my `aforesaid patentis;likely to be pushed vinwardly too 1 far so tobecome disengaged Vfromthe guide therefor, with the resultthat th'eplunger does not return tointerlocking position. It is a further object wherebythe movement'of theplunger will be'properlyflimited so. that the same will always belocated in the Iguide therefor andv thus Vbe .required to moveintoelocnking rela-v .togue iS .withdrawn- .tion ,with the fingers theAunlocking which .will Aappear l,as the description prodescribed `andlset forth yin the claims.

iReferringuparticularly lto Fig. l, I have shown the'sQ- calledfpull.over shaft l() of an A Xminster loom and have indicated thelower portion 'of "a sprocket 11 .which is supported and moves withi theshaft. The transporting chain l2 isformed of Single ,iinrlsiaahdeuuelinks 14. secured 4 to one ofthe double links 14 of each pair' of doublelinks is a tube `frame supporting iingerl lower end of vvvhichasl shownin Fig. I6 1s .provided with a slotll 4opening' into ysomewhat ,widerslot 17. T he outer end ofeach fingery may bey tapered as at 18 tovfacilitate*the*,operations to be described hereinafter. of my .presentinvention torprovide means Tuberame '19 is preferably made of a bracketor head2() asby means of screws 21. The .bracket has an upwardlyextending .Speel beatles' ,Partien .22 'Len which is mounted spool S.Formed as part of the head 2O is a U-shaped member 23 inserted withinthe metallic bar 19 and secured thereto by means of screw 24. The outerintermediate :portion of said member 23 is formed with `a vertical wall25 which is spaced from the vertical portion of the spool bearingportion 22 as shown in Fig. 2 and the lower end of said vwall 25 isprovided with a slot 26 to a'ord access to the slot 16 in the finger 15when the parts are in the position shown in Fig. 4. N

A spring pressed holding or locking plunger 27 has a head 28 adapted toextend through the enlarged slot 17 and engage the shoulders 29 definedby the narrower slot 16 when the parts are in their normal assembledposition such as indicated in Figs. 1 and 2. A compression spring 30' isinterposed between the head 28 and an upright wall 31 formed as part ofthe head 2()V and the effect of said Vcompression spring 30 is to movethe head 28 towardthe wall 25, or

l outwardly.

` is located the wall 25, so that vas the tube 'A framel is raised bythe clutch the'finger'15 tubeframe may be lowered'.

Under normal conditions the head 28V will be held by the spring 30within the slot 17 and will rest on the shoulders 29 as shown in Fig. 2.When it is desired to disconnect the tube frame from the transportingchain the head 28 will be moved to the left as viewed Ain Fig. 2 .untilsaid head is entirely clear of the shoulders 29, after which the Theclutch C as shown more particularly in Figs. 1,V 3 and 5 includes a body32ha'ving a lip 33 projecting fromv the underside thereof to Vlieunder'the bar 19. @Secured to the clutch is an upper stud 34 by means ofwhich the clutch'may be oscillated around a lower stud 35 which issecured lto the transporting arm 36 a' portion of which is shown inFig. 1. It is to be understood that said arm 3GV has anr inward movementto disconnect'the tube frame from the chain and then a downward movementtoV move 4the tube frame toward tuft forming posipatent and with thelexception of certainl details to be noted hereinafter forms no part ofmy present invention.'

In carrying my invention into effect I provide the clutch C with adownwardly and inwardly inclined wall 40 and provide the spool'bearing22 with a corresponding downwardly and outwardly inclined wall 41. Theseinclined wallscooperate to guide the fingers into the space between thespool bearing 22 and the wall'25. The clutch face 40 terminatesv in anoverhang 42'under which Vtion of the finger 15.

`engagement with to the left as viewed in Fig. 3. The lower portion ofthe spool bearing 22 is recessed as at 53 to receive the tongue 50 andit will be apparent from an inspection of Fig. 3 that because lof therecess 53 said tongue may extend slightly beyond the inner face of thelinger 15, so that there will be no possibility of the head 28 which isengaged by the tongue 5() extending'over any por- As the tube frame andclutch start downwardly, therefore, the head will be to the left of theinner face of the linger and will be held in this position throughoutthe movement of the tube frame the head 28 from moving out of theslot oropening 60, and there is therefore no chance for the lhead to getin sucha position that it may not return to proper position to haveinterlocking engagement with the lingers.

From the foregoing description I believe the operation of the devicewill be apparent.

The clutch is given the previously described downward movement with thepart-s in the position shown in Fig. 3, and then upon the return upwardmovement the clutch is moved away from the tube frame, that is, theclutch shown in Fig. 3 will be moved tothe right so that the head 28 maymove to the position shown in Fig. 2 to have holding theV correspondingnger 15.

From the foregoing itwill be seen that vI have provided a clutch andspool bearing so formed as to guide the finger l5-into the spaceproperly provided thereforand that the overhangl 42 operates to vprotectthe wall 25 and keep the same from having such engagement -with thefinger 15 as would prevent proper cooperation of the parts. Also,

especially formed, having a tongue to engage the -head 28 and movedownwardly through the slot 16. It will also be noted that by reason ofthe shoulder 61 I have prevented disengagement of the head 52 withrespect to the opening 60 in the bearing 22. Y

Having thus described my invention it will be seen that changes andmodifications may be made therein by those skilled in the art withoutdeparting from the spirit and scope of the invention and I do not wishto be limited to the details herein disclosed, but what I claim is:

l. In an Axminster loom having a transporting chain and a tube frame, afinger on the chain, a plunger on the tube frame to engage the finger tosupport the tube frame from the chain, said finger having a verticalslot in the lower portion thereof, a clutch to support the tube frame, astud carried by the clutch and having a thin vertical tongue to passthrough the slot in the finger to engage the plunger and move the latterout of engagement with the finger, said stud having a smooth cylindricalsurface to extend through the clutch to be capable of slidingtherethrough to adjusted angular and longitudinal position, said tonguethereby being capable of assuming a position to register with the slot,and means to hold the stud to the clutch.

2. In an Axminster loom having a transporting chain and a tube frame, afinger on the chain, a plunger on the tube frame to engage the finger tosupport the tube frame from the chain, said finger having a verticalslot in the lower portion thereof, a clutch to support the tube frame, astud carried by the clutch and having a thin vertical tongue to passthrough the slot in the finger to engage the plunger and move the latterout of engagement with the finger, said stud having a smooth cylindricalsurface to eX- tend through the clutch to be capable of slidingtherethrough to adjusted angular and longitudinal position, said tonguethereby being capable of assuming a position to register with the slot,meansto hold the vstud to the clutch, and a shoulder on the stud toreceive a force capable of moving the clutch toward the tube frame.

In testimony whereof I have hereunto affixed my signature.

ARTHUR P. PAINE.
